  • 1 can of Enviro-Safe 1234YF ProSeal with Leak Detector will treat 1 vehicle.
  • Forms a hard seal on metal, schrader valves, o’rings, gaskets, a/c condensers, evaporators, line sets and solder joints
  • Even though Proseal with Leak Detector for R1234YF can form a seal on the schrader valve, when you hook up to it the seal will release and allow you to use the schrader if necessary. 
  • If there is still Proseal with Leak Detector for R1234YF in the system it will reseal the schrader.
  • Proseal with Leak Detector for R1234YF uses a precisely selected, fluorescent-yellow dye that is highly visible and is the same dye used by auto makers in car A/Cs
  • While the dye is highly visible, and in most cases, able to be seen with the naked eye, the use of a blacklight as well as UV glasses does make it much more visible.
  • Before replacing expensive parts and labor, try Enviro-Safe Proseal with Leak Detector!
  • For best results, use Enviro-Safe Prodry for R1234YF BEFORE using the Enviro-Safe Proseal with Leak Detector for R1234YF to remove any moisture in your system. 
  • Moisture is corrosive and no one wants that in their system!
  • The can itself has a R134 top on it as shown in the picture so you will need a hose with a R134 top tap and R1234yf vehicle connection.
